Problem crops up about weekly on HP-UX 11.23 box,Tectia 6.1.4.83. Find large number (dozens) of ghost connections on system. Have several other HP-UX boxes (same hardware, versions,connection profiles,similar kernel,tcp stack params) running with no issues.

Restart of ssh-server-g3 'fixes', ulimit -n returns 2048 (in similar post). The majority of the thousands of connections involved are app driven sftp, using a mix of both pwd and pub-key.

Thoughts on why connections are not being released? Any ideas on what we should check,do?
Understand this may not be Tectia issue... but any input appreciated.
